The effects of neuropeptide Y (NPY) on the Ca2+ current of enzymatically dispersed neuronal somata from bullfrog paravertebral sympathetic ganglia were investigated using the patch-clamp technique. In C neurons, NPY induced a concentration-dependent decrease in the amplitude of the Ca2+ current and induced a slow biphasic current rising phase. Upon removal of NPY these parameters returned to near control values. NPY had no discernable effect on the Ca2+ current recorded in B neurons.
